It seems like what he's looking for is a clause which provides protection
somewhere between that of the GPL and LGPL. Specifically, the LGPL's
license compatibility but with the GPL's assurance that the code will stay
free. The GPL's arbitrary standard to maintain freeness is the GPL
itself. What he needs is another standard. OSI Certified licenses seem
to be a viable solution (oh gods, don't let Eric hear me say that..)
Or you could just as easily incorporate a variation on the OSD/DFSG into
the license itself to ensure that you have full control over what the
definition of "free" within the scope of your license actually is. This
is the best option most likely, though the most work.
As Richard has pointed out a few times in the past, it may be less trouble
to write your own license to avoid confusions.

Only in your understanding of what he wants. =)

That should cover it I think. Still, you're leaving the judgement call as
to whether or not software is free enough in the hands of OSI who may or
may not make decisions you agree with. While they thankfully rejected
Sun's blatant subversion of the free software community with their
"Community License", they did accept Apple's termination-anytime-we-want
clause. It's your call to make, but it is my (non-legal) opinion the
above should be good enough if it is indeed what you want.
Given the number of people who seem to want the same and try to cook up
their own license as a result (Debian is very familiar with these - most
of them whose authors can no longer be located are unfortunately relegated
to non-free status even though it's almost certainly not the intent of
their authors), it might almost make sense for someone to sit down and
write the kind of license you and others are looking for and hope to hell
people will use it and at least slow the license proliferation problem
down a bit. Ironic to suggest a new license as a way to help curb license
proliferation, but there you have it. =)
